The Chicago Bulls are exploring avenues to acquire Los Angeles Lakers forward Pau Gasol before Thursday's trade deadline, according to sources close to the situation.

The Bulls have long hoped to wedge themselves into the trade running for Orlando Magic star Dwight Howard, but sources told ESPN.com that Howard's well-chronicled lack of interest in a trade to Chicago has prompted the Bulls to switch their focus to Gasol in advance of Thursday's 3 p.m. ET deadline.

Sources say that the Lakers, however, have limited interest in the players Chicago would be offering, starting with Bulls forward Carlos Boozer.

So the Bulls would have to recruit at least one more team to the discussions to have any shot at Gasol, sources said, with the Lakers known to be insistent on getting back at least one certifiable star if they consent to trade the Spaniard.

Sources say that the Lakers, furthermore, are talking to other teams about Gasol in advance.
